through the night. At Cromer on Oct. 24th three Thrushes struck 
the lantern during the night; on the 30th four, and on Noy. 16th 
five others. At the Newarp, Nov. 28th, 9a.m.,six Blackbirds passed. 
At the Kentish Knock, Nov. 18th, one Thrush killed. At the Nore, 
Noy. 7th, four Blackbirds, going W.S.W.; Nov. 8rd, Fieldfares. 
At the North Foreland, Noy. 21st, 1 a.m., E.S E., snow, one Black- 
bird killed. At the Gull-stream, Nov. 21st, cloudy and showers of 
snow, Starlings, Blackbirds, and Thrushes in the vicinity of light 
from 1 to4a.m.; six Starlings, four Thrushes, and one Blackbird 
killed. At the South-sand Head, Oct. 12th, dense fog, many 
Thrushes; several killed. General line of migration, with few 
exceptions, E. to W., carried on both by day and night; a con- 
siderable proportion, however, appear to arrive from daybreak to 
10 a.m. Migration of Thrush extending over seventy-seven days, 
from Oct. Ist at Teesmouth to Dec. 16th at the Leman and Ower; 
of Redwing, sixty-five days, from Sept. 11th at the Longstone to 
Dec. 2nd at Teesmouth; of Fieldfare, twenty-eight days, from 
Nov. 3rd at the Nore to Dec. 1st at Teesmouth ;+ of Blackbird, 
seventy-two days, from Sept. 24th at the Outer Dowsing to Dec. 5th 
at Farn Islands.{ On Oct. 29th, S.E. and E., T'urdus iliacus crossed 
Heligoland in large numbers, “thousands and thousands passing 
on overhead; the same day, 7’. torquatus, “afew”; J’. merula and 
T. musicus, “limited numbers”; “ 7’. diacus descending from 
invisible heights down to about one hundred feet above island,— 
three hundred feet above the sea,—then all of them passing on; 
when atmosphere got clear again, in afternoon, passage ceased.” 
Again on the night of the 30th, N.N.E., “enormous number of 
Turdide passing overhead.” 
REDBREAST, WHITETHROAT, WrEN.—The same notes in the 
reports applying generally to the three species, it is not necessary 
to treat them separately. At Coquet Island, on Sept. 13th, 11 p.m., 
two Redbreasts struck glass, not killed. At Hunstanton, on 
t+ Mr. W. Eagle Clarke reports that on the 24th of January last large numbers 
of Fieldfares were seen between Easington and Kilnsea, near Spurn Point, and as they 
were the first seen in the neighbourhood this season they were uo doubt immigrants, 
more particularly as the locality in which they were seen is one where they are only 
observed during or immediately after arrival. Large flocks appeared also in North- 
East Lincolnshire during the last fortnight in January, so far as my own observations 
go, composed entirely of old birds. Mr. Gatke also writes, “ All January through, 
night from 10th to 11th, great many from the east; 21st to 24th, the same.”—J. C. 
+ Numbers of fine old cock Blackbirds arrived at Spurn during the latter part of 
January, and early in February at the same time with the Fieldfares.—J. C,
